All India Institute of Medical Sciences, popularly known as AIIMS is one of the most sought after medical colleges in India. Medical aspirants of not just India but across the world aspire to get through one of the AIIMS campuses, especially the oldest and top-ranked ones. At present, there are 23 AIIMS campuses in India out of which 19 are functional and the rest are under construction.
AIIMS in India was established under the Act of Parliament, 1956. The functions and objectives of the institute were defined in this act, thus giving it an autonomous status. Later in 2003, the Pradhan Mantri Swasthya Suraksha Yojana (PMSSY) planted the seeds for expansion of the most esteemed medical institution in India and led to the establishment of other AIIMS campuses.
